Specialist Purging Technology

The Complete Purging System
The NEPS1000 ADVANTAGE is designed to maximise the dry gas purging process for humidity removal, with a host of capabilities and functionality for effective and efficient control during the purging operation.

Easy Operation

NEPS1000 ADVANTAGE is fully self-contained. Simply connect a dry gas source to the inlet connection and the equipment to the outlet port. The NEPS1000 ADVANTAGE is ready to operate.

Economic Gas Use

One of the NEPS1000 ADVANTAGE benefits is its use of the purge gas used for purging. By using a single pipe connection the purge gas is controlled and dispersed throughout the Instrument or System being purged. During the depressurisation phase of purging the purge gas is isolated.

User Friendly

The NEPS1000 ADVANTAGE has simple to use selectable programming, which can be set to view process control values and display dewpoint measurements in ºC or ºF with pressure in Kpa or psi. Highly visible liquid displays provide constant information and readouts during operation and use.

Equipment Leak Testing

The NEPS1000 ADVANTAGE comes with a selection of four in built leak testing capabilities to verify the sealing standard of the equipment to be purged. Pressure testing can be conducted in pressures from 10.3 Kpa (1.5 psi) to 34.4 Kpa (5.0 psi). Pressure leakrate display resolution is 0.01 psi.

Gas Quality Testing

The dryness of the gas is important to the effectiveness of the purging operation and NEPS1000 ADVANTAGE dewpoint monitor can be used to check the dryness of the gas prior to commencing the purging operation.

Universal Voltage

The NEPS1000 ADVANTAGE can be operated from global country voltages and frequencies ranging from 100 to 230 VAC at 50-60 Hz.

Why Purge with NEPS1000

Modern systems that use printed circuit boards, wires, electronic components, rubbers and plastics in their construction will have potentially significant amounts of moisture. The amount of in built moisture is often described as “hygroscopic moisture”. This can be significant in comparison to the moisture (water vapour) contained within the air.

Single Connection Purging

Traditional conditioning with dry nitrogen, gas or air depends on the flow of gas from an entry connection to an outlet port. In this mode the gas will follow the simplest and easiest path to the outlet connection. This can often lead to “pockets” of unconditioned gas.

Using NEPS1000 ADVANTAGE the mode of operation changes to a more efficient single connection purging process which also uses a choice of three selectable pressure cycles to ensure the dry gas influences all the space volume within an equipment.
